Utilization of wild relatives in the genetic improvement of Arachis hypogaea L. : 8. Synthetic amphidiploids and their importance in interspecific breeding

A K Singh. Theor Appl Genet. 1986 Jul.

Abstract

Synthetic amphidiploids were established in 32 combinations involving 8 diploid wild species representing both A and B genomes of section Arachis. Bivalent and multivalent associations in the amphidiploids of 7 A genome species confirm that these species have identical genomes. Contrastingly, high bivalent frequencies in amphidiploids involving the A and B genome species suggest that A. batizocoi has a distinct 'B' genome that is partially homologous to the other genome 'A' represented in the rest of the species. Crossability, chromosome pairing and pollen and pod fertility in hybrids between A. hypogaea and amphidiploids have revealed that these amphidiploids can be used as a genetic bridge for the transfer of genes from the wild species into the cultivated groundnut.
